The Free Speech Coalition, an adult industry trade group, called a filming moratorium Friday — the second in a month — after a performer tested positive for HIV. The group called a weeklong moratorium last month after actress Cameron Bay tested HIV-positive.

A second performer, Rod Daily, who is romantically linked to Bay, came forward on Twitter and told the Los Angeles Daily News that he too had tested positive — but that case was not officially reported to the industry group and did not result in a new moratorium. Friday’s call to stop shooting came after a third performer tested positive and was reported to the Free Speech Coalition by an industry-affiliated doctor.

Michael Weinstein, president of the AIDS Healthcare Foundation — a group that backed a voter-approved mandate to use condoms in filming in Los Angeles County last year and is now pushing for a statewide requirement — said a fourth adult film performer contacted his group in the last week.
